Bacteria that live on iron were found for the first time at three well-known vent sites along the Mid-Atlantic Ridge, one of the longest undersea mountain ranges in the world. Scientists report that these ...

(Phys.org) —The release of wastes associated with nuclear reprocessing from storage facilities into the underlying sediments and groundwater is an important environmental concern. Scientists working with ...

Scientists at Curtin University have chronicled the genesis of a particular type of iron deposit in the state's north, finding that the valuable mineral formed relatively late in Western Australia's evolution.

Ian Salter from the Alfred Wegener Institute and a team of international collaborators discovered that iron fertilization promotes the growth of shelled organisms. In a naturally iron-fertilized system in ...

In heme biosynthesis, the terminal step is the insertion of ferrous iron into protoporphyrin IX (PPIX) by the enzyme ferrochelatase. Under physiological conditions, small amounts of zinc protoporphyrin IX (ZnPP) are formed ...

Rice, maize, soybeans and wheat are the main source of nutrients for over 2 billion people living in poor countries. But with climate change and the rising amount of CO2 in the air we breathe, their already low nutrient value ...

A study published in Scienceby researchers from the U.S. Department of Energy's Argonne National Laboratory and co-authored by Georgia Tech may dramatically shift our understanding of the complex dance of microbes and minerals ...

High concentrations of dissolved iron from abandoned coal mines in Pennsylvania have been contaminating some of the commonwealth's streams and rivers for many years, potentially affecting aquatic habitats ...

The body's assailants are cleverer than previously thought. New research from Lund University in Sweden shows for the first time how bacteria in the airways can help each other replenish vital iron. The bacteria thereby increase ...

Hexavalent chromium is a major environmental contaminant at several Department of Energy (DOE) sites as well as other sites around the world. Iron-reducing bacteria can convert the oxidized form of iron in ...

You don't have to listen to heavy-metal music to be a metal head. The human brain harbors far more copper, iron and zinc than anywhere else in the body. Abnormally high levels of these metals can lead to ...

With news reports of toxic cadmium-tainted rice in China, a new study describes a protein that transports metals in Arabidopsis plants and holds promise for developing iron-rich but cadmium-free crops.
